On New Year's Day and New Year's Eve, employee Sui An mistakenly sent a message to his best friend, "Baby, I'm off work soon," to a large company group, causing the whole company to boo. The boss Ji Ming, who has always been aloof, got drunk and blocked her door late at night, asking aggrievedly about the conditions of her love rival. Sui An was shocked to realize that the boss had a crush on her. From being alone at the annual party to meeting again on a blind date, Ji Ming pursues love deeply, and Sui An also discovers during the relationship that the boss who has accompanied her all the way from the start-up company has been in love for five years. The two resolved their misunderstandings, turned from superiors in the workplace into sweet lovers, and started a healing love that goes both ways.
